Sfn.cn Test Results
sfn.cn Mobile Usability: 96/100
Quick overview:
Configure the viewport
Your page specifies a fixed-width mobile viewport. Consider using a responsive viewport to allow your page to render properly on all devices.
Configuring a viewport specifying width=device-width instead of width=320 will allow your page to adapt for devices of various widths. This may require additional work if the styling on your page relies on a fixed-width layout.
